The Schedule referred to in these Letters Patent and making part of thesame.

To all whom, 'it concern i `Be it knownthat I, J osnPH D1ek,'.lr.,formerly of Canton, Stark county, Ohio, but now residing in Oshawa,Ontario county, in the Province of Ontario,

have invented certain new and useful Improvements in Harvester-Rakes;and I do hereby declare the following to be a full, clear, and exactdescription of the same, reference beinghad to the accompanying drawing,makingl a part of this specification, in which- 'Figure l is aperspective view, taken frm the rear grain-side of the platform, andshowing the rake in the position it occupies at the end of its dischargeor delivery-stroke and before rising for the return-stroke;

Figure 2 is a side elevation ofthe same;

Figure 3 is a perspective view of the bed-plate detached; and f Figures4 4 are detached views, showing 'the oper- A ation ofthe rake-latchhereinafter described.-

reference to the iguresof the drawing, in which- A represents a'quadrantplatform, which is to be connected with the finger-beam of a reaper inany usual or desired manner, and the outer or grain-side of which iscurved in the arc of a circle, of which the rake-pivot is the centre,'orotherwise made to conform substantiallly to the path described bytheouter end of the rake in passing over the same.

B is an angular bed-plate bolted or otherwise secured tothe inner frontcorner of the platform or inner end of the linger-beam, or beam andplatform,

` as may be preferred. Said bed-plate is represented in the detachedview, iig. 3, and is composed of or provided with the lower flange orbase, a, which rests upou and is bolted to the linger-beam or platform,an elevated table, c', bearings b b', for the driving and bevel orcrank-wheel shafts, rake-pivot c, stop and latch-lugs d d'aud d2, allformed upon or otherwise connected therewith, for purposes hereinafterexplained.

The rake-pivot c has mounted upon it the vibrating sector-arms C andtubular carrying-arm D, the former provided at its outer' or swingingend with a toothed sector, O', and the latter carrying or having mountedin it the rake-stale or arm E, which is armed with a segment-pinion, E,the teeth of which engage with and atravel over those of the sector-armfor imparting the necessary rising and falling movements to therake-head E2 in a manner that has been fully explained in the patentreferred to. v

D is a heel-extension of the tubular arm D, to which the pitman whichvibrates the rake is connected, as hereinafter described.- l

vThe outer end of arm D is provided with a -lug o r lugs, e, in which ispivoted one end of a latch, f, the

opposite or free end of which rests upon the sectorl arm, or enters aslot, g, therein, and, when engaged with the sector-arm, serves to latchor lock the rakearm in its elevated position, and to prevent anymovement of the tubular carrying-arm relative to the sectorarin duringthe return-stroke of the rake.

A friction-roller, 7a', on the end of a slotted adjustable arm, h,serves to lift the latch f out of its socket `or slot, g, atV the properinstant to allow'the rake to descend upon the brwild edge of theplatform, when the inclined end of the latch rises readily andea'silyforward stroke, and in such m'anner that the forward movement shallterminate and the discharge or delivery-stroke shall begin the instantthe rake reaches the platform;

The throw of the sector-arm C is regulated by setv screws, d d, in thelugs or ears, el d, lof the baseplate B.

i is a latch-lever pivoted in lug d on the bed-plate, and provided atits rear end L'with an adjustable latchhead or hook, i, which engageswith a lug or. ear, j, on the sector-arm G, at the instant the lattercompletes its forward or return-movement, and reaches theregulating-stop or set-screw d, and serves to hold said arm O againstany backward movement until the tubular carrying-arm D has completed itsforward movement, travelling over the sector-arm, and the -rake hasthereby been caused to descend upon the platform, at which instant thelatch is raised, and the sector-arm released by means of a lug or cam,J', on the lower face of the bevel and crank-wheel,striking upon anddepressing the curved-heel extension of latch-lever fi, thereby leavingthe rakeand its carrying-arms C and D free for their delivery-movement.

The driving-shaft F, mounted in bearings, b b, of the bed-plate B, isdesigned to be connected, by a tumbling sliding extension, withdriving-mechanism on the main frame of the machine, in such manner as toadapt: it to operate in connection with a hinged platform andfinger-beam.

The outer or platform-end of said shaft is armed with u bevel-pinion,whielLengn-ges with :md drires the bevel-wheel G, tht-'shaft of whiehhns its bearings in the buse-plate ll, :it b'. Suid wheel is provided onits upper thee with the ernnk-nrm ll, upon whieh is mounted n tubularcrunk-box, i, one nrm ot'wheh embraces the pitmnn .l, und is mndeudjustnble thereon,

for varying the. length ot' the pitnmn, by mezms of ner, for the purposeofvnrying the throw ofthe r-.tke-

head, ns desired.

It will be seen from the dum-ings thnt the ranke-pivot is loeztted onthebnse-plnte, in rezn ot' the driving :md crank-wheel shaft, :it atpoint on the matinframe side of the latter.

The connection ot' the mko with the driviiigcg-ernnl.f is marde throughn heel or ontwzu'd extension of the ranke-carrying zum, its described,:md the relation ot' parts is suoli that the eratnk passes one of itseentres just :titer the rake hats completed its deliver \'strdie,:md'hnsbeen rztised :md looked for its return-stroke, :nid the otherutter it hns eompleted its retnrn-stmlie and when the ratke isdescending upon the plnttorm into position t'or itsdiselmrge-nxoi'emelit5 :unl the movement ot' the e1-:mk being; in thedireetion indicated by th mrow, tig. ll, the position ot' the. pitmam,:nld the path ot' morenient of the eratnli-:n'ln nt the institut theernnk posses its Idstein-med centre, nre approaching :t right ongle tothe heel 1l, und n diree-t Aaction of the ern-nk is consequently:ttm-ined just zit that point in the movement ofthe rnke where the s.grezttest mnount of power und the highest velocity of movement ot' theruhe are required; :md when the crank is pztssing its centres it isrelieved of :ill weight or movement tha-t would obstruct it, the weightot' the rake, in descending upon the platform, serving; rather to assistthan retard the movement of the crunk in passing the centre lust abovedescribed.
